Two 17-year-olds suspected of plotting a shooting spree at their high school were obsessed with the mass killings at Columbine High School in Colorado, officials said Friday. The teens were arrested Thursday at East High School after a resource officer at the school learned they had homemade bombs and weapons at their homes. (AP Photo/ Morry Gash)
